Balloon sinus dilation is a minimally invasive treatment for chronic or recurrent sinusitis. In a balloon sinus dilation procedure, your physician uses a small balloon to dilate or expand the sinus opening and drainage pathways to restore sinus drainage. Balloon sinus dilation is a comfortable procedure that can be performed right here in our office. The local anesthesia you’ll receive is similar to what is used in dental offices. In many cases it offers instant and lasting relief. This option can also reduce your treatment costs compared to alternative procedures.
